I have a Profibus network with 1 master and 8 slaves (each PLC with alarm_S data), now I can get the master PLC connected to the WinCC but the slaves won't connect.
When I compile the OS it says that I havn't configured a network connection for the slave PLC's, but they already communicate with the master, so the network is fine.

I'll have to look for the Simatic net DVD them. Hope someone here has one (bit early now, nobody's here yet but me)

Ethernet is for the following project (this is type installation and I'm not allowed to change many things at once)

Copying evertyhing to the master (and use it as a data concentrator) is not what I want because every cel has it's own plc and sometimes we have 2 cells but sometimes 20 and want it to be as flexible as possible.
That's why the alarms (alarm_s) are in the slaves.
